Abstract

Einrichtung zur Abwasserreinigung, mit einem Becken (1) für das Abwasser, in dem eine Strahlpumpe (4) angeordnet ist, deren Saugseite (9) mit einer Luftleitung (10) zur Zuführung von Luft verbunden und deren Druckseite (8) in das Becken gerichtet ist. Es sind Mittel zur Umschaltung der Saugseite (19) von der Luftleitung (10) zu dem Abwasser in dem Behälter vorgesehen. Auf diese Weise kann die Strahlpumpe sowohl zum Eintragen von Luft in das Abwasser in einer aeroben Phase als auch zur Bewegung und Durchmischung des Abwassers in einer anaeroben Phase durch Ansaugen von Abwasser verwendet werden. Die Einrichtung ist daher besonders einfach, zuverlässig, dauerhaft und preisgünstig.
